Fig. 5

a DO content of tap water and groundwater (n = 13). The measurements of DO content were taken from distinct samples. b Photograph of the continuous flow photocatalytic disinfection. c Groundwater disinfection performance (n = 11) of the continuous flow system. The measurements of bacterial colonies were taken from distinct samples. d Stability of the continuous flow system. The inset images are the plating photographs of water samples after 62, 63, and 64 h photocatalytic disinfection. e Stability comparison of IS/MB-20 with other photocatalysts reported. f Plating photographs showing the disinfection effect of different dosages of NaOCl in 37.2 L groundwater. g Dosage of NaOCl and IS/MB-20 required to produce 37.2 L of bacteria-free water. Data are shown as box-and-whisker plots, with the median represented by the central line inside each box, the 25th and 75th percentiles represented by the edges of the box, and the whiskers extending to the most extreme data points.
